Abstract
In the prior art, it is necessary to transmit high-intensity currents between two printed circuit boards arranged parallel to one another and also to mechanically fix the two printed circuit boards to one another, wherein their spacing can vary within predetermined tolerances. This object is achieved by a pin-shaped printed circuit board connector (1) having a pin axis (a), which can be reversibly deformed at least slightly, wherein the printed circuit board connector (1) has at least one first slit (S1) which begins at the insertion-side end (12) and extends through the pin axis (a) in the direction of a printed circuit board connection region (111), through which at least two sections (14) pointing in the insertion direction are formed. In particular, the printed circuit board connector (1) may additionally have a second slit (S2) of this type, which intersects the first slit (S1), in particular at right angles, in the pin axis (a), thereby forming even four segments (14) directed in the insertion direction.
Description
Technical Field
The present invention relates to a printed circuit board connector according to the preamble of independent claim 1.
Such a printed circuit board connector can be used to fix two printed circuit boards arranged parallel to each other at a desired pitch to each other and to make electrical contact with each other. In particular, the printed circuit board plug connector is then used to transmit high amperage currents between two printed circuit boards. The term "high amperage" means here and in the following that each printed circuit board connector is capable of transmitting, for example, at least 10 amps, in particular at least 16 amps, for example at least 24 amps, preferably at least 32 amps, and in a particularly preferred design even 40 amps and more.
Background
In the prior art, it is known, for example from document WO2018/006892a1, to electrically and mechanically connect printed circuit boards to one another at their ground contacts by means of screws, in order to be able to lead out interference signals on the shortest path to the housing ground. In order to compensate for geometric deviations which inevitably occur within predetermined tolerances during the production of the electrical device due to varying housing dimensions, it is proposed to connect these bolts to the housing by means of plug connections of variable insertion depth, for example by means of tulip-like supporting bolts.
The disadvantage of this prior art is that, although housing tolerances can be compensated in this way, the distance between the individual printed circuit boards, which in the case of this design is already predetermined by the shape of the screw, cannot be compensated. However, it has been shown in many cases that these distances also vary somewhat when building electrical equipment. Therefore, a mechanical fixation and an electrical contact with each other between the two printed circuit boards mentioned at the outset are required. In this case, a corresponding mechanical tolerance compensation is additionally ensured, even in the case of simultaneous transmission of the high-intensity currents.
The german patent and trademark office retrieves the following prior art in the priority application of the present application: HARTING: DIN signal high current FS40A for M-flat; HARTING: selection guide for mezzanine applications, edition 2016-03-18 (version 2) and HARTING: the connector DIN41612, version 2017-03-10 (version 03.11).
Disclosure of Invention
The object of the present invention is to propose a printed circuit board connector which on the one hand is capable of transmitting high-intensity currents between two printed circuit boards arranged parallel to one another and which on the other hand is suitable for mechanically fixing the two printed circuit boards to one another, wherein the spacing thereof can vary within predetermined tolerances.
Here and in the following, the term "high amperage" particularly means that each printed circuit board connector is capable of transmitting a current of, for example, at least 10 amps, particularly at least 16 amps, such as at least 24 amps, preferably at least 32 amps, and particularly preferably even 40 amps and more.
This object is achieved by the features of the independent claims.
A printed circuit board connector is designed as a pin contact with a pin axis and has a printed circuit board connection region at its connection-side end. Oppositely, it has at the end portion of its insertion-side end a tapered insertion region toward the insertion-side end. The printed circuit board connector has a connection portion between the printed circuit board connection region and the insertion region.
The printed circuit board connector furthermore has at least one first slot which starts at the insertion-side end and extends by its pin axis in the direction of the printed circuit board connection region.
The printed circuit board connector may have symmetry at least in some regions and may be rotationally symmetrical and/or mirror-symmetrical, in particular axially symmetrical, at least in this region.
Preferably, the pin axis may be an axis of symmetry of the printed circuit board connector or at least a part of the printed circuit board connector.
Advantageous embodiments of the invention are specified in the dependent claims.
Advantageously, the printed circuit board connector with its printed circuit board connection region protrudes through the first through-contact opening of the first printed circuit board and here conductively contacts the first contact region arranged at the through-contact opening and in particular also in the through-contact opening.
It is particularly advantageous that in the printed circuit board connector at least two, in particular identical, separate sections of the printed circuit board connector in the plug-in direction are formed by the at least one slit in its connection region and in the plug-in region. The at least two segments are each directed towards the insertion-side end and can be moved with their individual ends at least slightly towards each other by at least slight elastic deformation of the printed circuit board connector, for example by compressing the insertion region of the printed circuit board connector.
On the one hand, this is particularly advantageous, since the contact openings plugged onto the printed circuit board connector via the plug-in area, for example the through-contact openings of the second printed circuit board, can thereby be held on the connection portion of the printed circuit board connector movably along the pin axis, at least within a desired tolerance range.
On the other hand, this is advantageous, since in this way the printed circuit board connector is pressed with a corresponding restoring force from the inside by its at least slight elastic deformation towards the contact material of the second through-contact opening of the second printed circuit board and thus a correspondingly high contact force for the electrical contact can be applied with a correspondingly high electrical conductivity.
In a preferred embodiment, the printed circuit board connector additionally has a second slot, which also starts at the insertion-side end and extends in the direction of the printed circuit board connection region, said second slot intersecting the first slot at the pin axis, in particular at right angles. This is particularly advantageous because the flexibility of the printed circuit board connector is thereby increased. Finally, four, in particular identical segments of the printed circuit board connector are formed, which can be deflected, in particular uniformly, for example at least slightly elastically in the direction of the pin axis, under the application of a corresponding counter force.
Of course, the printed circuit board connector may have one or more further slots in addition to the first and second slots, i.e. there may be three, four, five, n, where n represents any natural number. These may result in a corresponding number of segments. It should be noted here, however, that not only the contact area of the printed circuit board connector but also the reaction force exerted to resist deformation decreases with the number and/or width of the slits.
In practice, therefore, the variant of two slits which intersect at right angles on the pin axis has proven to be particularly advantageous. Four identical segments can thereby be formed in the insertion portion and the connection portion of the printed circuit board connector, which segments deform uniformly under uniform load.
In a further preferred embodiment, the slit/slits terminate either in the connecting section or at the latest at the end of the connecting section. This is particularly advantageous since the printed circuit board connection region provided for contacting the first printed circuit board is designed solid in this way, since it is therefore free of slits. Finally, it can thus be soldered particularly well to the first printed circuit board.
In order to allow said elastic deformation of the second printed circuit board during insertion by means of the contact openings, for example of the second printed circuit board, the printed circuit board connector is advantageously formed from an at least slightly reversibly deformable electrically conductive material. In particular, the printed circuit board connector may be formed of metal, which advantageously facilitates these mechanical properties as well as electrical conductivity.
In an advantageous embodiment, the printed circuit board connector is a turned part in its basic shape. As a result, it can be produced very stably and automatically and therefore cost-effectively. In particular, the at least one slit can be introduced into the pin contact only with little expenditure, for example by sawing or milling.
A system is composed of at least one first printed circuit board and at least one printed circuit board connector as described above. The first printed circuit board may have at least one through contact opening and at least one first electrical contact area arranged at the first through opening. In particular, the first contact region can also cover an inner side of the respective through-contact opening.
In an advantageous embodiment, the at least one printed circuit board connector may have a circumferential collar between its printed circuit board connection region and its connection portion, by means of which circumferential collar the printed circuit board connector is placed on the first printed circuit board. The printed circuit board connector is thereby connected with the first printed circuit board in a mechanically particularly stable manner. Furthermore, the printed circuit board connector may also be in electrical contact with the contact areas of the through-contact openings of the first printed circuit board by means of its collar, in particular may be soldered thereto, thereby increasing the common contact area and thus increasing the amperage of the current which may be transmitted through it.
Furthermore, the at least one printed circuit board connector may be inserted through the second through-contact opening of the second printed circuit board on the insertion side, that is to say first with its insertion region, and electrically contact the second printed circuit board at a second contact region arranged at the second through-contact opening.
In this case, the insertion region of the at least one printed circuit board connector is at least slightly elastically compressed by at least slight deformation of the connection portion under the application of a corresponding reaction force and is pressed against the second contact region by means of this reaction force in order to contact the second contact region with a correspondingly high electrical conductivity.
By means of at least slight deformability of the printed circuit board connector, the second printed circuit board is held on the printed circuit board connector movably by means of its at least one through-contact opening within a predetermined tolerance range in the direction of the first printed circuit board and/or in the opposite direction. This is particularly advantageous in order to compensate for tolerances when building the device. Finally, due to this type of construction, the second printed circuit board can be moved towards the first printed circuit board or away from the first printed circuit board within a predetermined tolerance range even in the assembled state. By means of its at least one slit and in particular its at least slightly reversibly deformable material, in particular metal, the printed circuit board connector finally has at least the slight deformability required for this.

fig. 1c is a printed circuit board connector with two printed circuit boards shown in cross-section;
fig. 2a-2b are structures consisting of two printed circuit boards connected to each other by a plurality of printed circuit board connectors;

Detailed Description
These figures contain partially simplified schematic diagrams. In part, identical reference numerals are used for identical, but possibly different, elements. Different views of the same element may be scaled differently.
Fig. 1a-1b show a printed circuit board connector 1.
The printed circuit board connector 1 is designed as a pin contact with a pin axis a shown in fig. 1b and is made of an electrically conductive material that is at least slightly reversibly deformable. In the present case, the printed circuit board connector 1 is made of metal, but different materials, such as conductive or conductively coated plastic, are also conceivable.
The printed board connector 1 has a connection-side end 11 and an insertion-side end 12. At its connection-side end 11, the printed circuit board connector has a printed circuit board connection region 111. Oppositely, it has an insertion region 122 which tapers towards the insertion-side end 12. Between the printed circuit board connection region 111 and the insertion region 122, the printed circuit board connector 1 has a pin-shaped connection portion 10, the region of which is graphically highlighted by means of curly brackets in fig. 1 b. Between the connection portion 10 and the printed circuit board connection area 111, the printed circuit board connector 1 has a cylindrical circumferential collar 13.
The printed circuit board connector 1 has two slits S1, S2 starting at the insertion-side end 12 and extending in the direction of the printed circuit board connection region 111 through the pin axis a, namely a first slit S1 and a second slit S2, which cross at right angles on the pin axis and end in the connection part 10. Four identical segments 14 are thus formed in the printed circuit board connector 1, which can be seen particularly clearly in fig. 1 a. At the insertion-side end 12 of the printed circuit board connector 1, each of the four segments 14 has a separate end which, for the sake of clarity, is not provided with a separate reference numeral. The segments 14 point with their individual ends jointly in the insertion direction of the printed circuit board connector 1.
Fig. 1c shows in cross-section a printed circuit board connector 1 having two printed circuit boards 21, 22, a first printed circuit board 21 and a second printed circuit board 22, connected by means of it. The two printed circuit boards 21, 22 each have a plurality of through- contact openings 210, 220.
The printed circuit board connector 1 is inserted with its printed circuit board connection region 111 through one of the through-going contact openings 210 of the first printed circuit board 21 on the one hand and is also soldered on the inside to a contact region 228 (shown in fig. 2 c) located thereon. At the same time it is placed on the second printed circuit board 22 by its collar 13.
It can furthermore be readily seen that, on the other hand, in order to electrically connect the two printed circuit boards 21, 22 with their insertion regions 122, the printed circuit board connector 1 is previously guided through the through-contact openings 220 of the second printed circuit board 22 and is now pierced (durchgreift) in an electrically contacting manner by the portions of its connection portions 10 adjacent to the insertion regions 122. In this case, when the insertion region 122 is inserted into the through-contact opening 220, the respective individual ends of the four segments 14 are moved toward one another with slight elastic deformation of the segments 14. A corresponding counter force is thereby exerted by the segment 14, by means of which the segment 14 is pressed against the contact material arranged in the through-opening 220, which is an integral part of the contact region 228.
In this way, a mechanical fixation and an electrical contact are made between the two printed circuit boards 21, 22, wherein the electrical contact has a particularly good electrical conductivity due to the correspondingly high contact force. The mechanical fixing is at the same time provided with the desired tolerances.
Due to this deformation, the four segments 14 point slightly towards one another with their individual ends in the inserted state. In the inserted state, the printed circuit board connector 1 is thus slightly tapered towards its insertion region 12. In the inserted state, on the other hand, it widens slightly in the direction of its printed circuit board connection region 111.
The second printed circuit board 22 may thus be inserted somewhat deeper, but ideally not arbitrarily deep, within predetermined tolerances, onto the connection area 10 of the printed circuit board connector 1. In the opposite direction, i.e. in the insertion direction, the second printed circuit board 22 can also be pulled away from it again and/or removed completely from it. In other words, the printed circuit board connector 1 may be inserted with its connection region 10 somewhat deeper into the through-contact opening 220 of the second printed circuit board 22 or may be pulled out of it again somewhat further. When the printed circuit board connector 1 is inserted deeper, the segments 14 move towards each other with their free ends in a somewhat more resilient manner. On a slight pull-out of the printed circuit board connector 1, the segments move away from each other again to a slightly greater extent. This gives a tolerance range within which the insertion depth can vary. The distance D between the two printed circuit boards 21, 22 can thus also be varied within tolerances predetermined thereby, while at the same time ensuring an electrical contact for high current strengths, for example >10 amperes.
Fig. 2a and 2b show, in an oblique view and in a side view, two printed circuit boards 21, 22 arranged parallel to one another, which have conductor tracks 213, 223 located thereon. As explained in detail above by means of an example of the printed circuit board connector 1, the two printed circuit boards 21, 22 are mechanically and electrically connected to each other via a plurality of printed circuit board connectors 1. Here, the two conductor circuits 213 and 123 are electrically connected to each other.
Fig. 2c shows the structure in a top view. It can clearly be seen how the printed circuit board connector 1 is passed through the through-contact opening 220 of the second printed circuit board 22 and protrudes with its insertion-side end 12 out of the second printed circuit board 22, whereby the printed circuit board connector is in electrical contact with the respective conductor circuit 223 at the contact area 228 of the second printed circuit board.
Although the various aspects or features of the invention are shown in the drawings in combination, respectively, it will be clear to the skilled person that the combinations shown and discussed are not the only possible combinations, unless otherwise specified. In particular, units or feature complexes from different embodiments that correspond to one another may be interchanged with one another.
